Alex bought a new aquarium. He is in the process of setting it up. The aquarium is in the shape of a right rectangular

mr Goodwill [35]

Answer:

Step-by-step explanation:

Formula for volume of a right rectangular prism is;

V = lwh

Where;

l is length

w is width

h is height

We are given l = 367; w = 24; h = 19

Thus;

Volume is;

V_full = 367 × 24 × 19

V_full = 167352 in³

We are told that Alex filled the aquarium with 6039 in³ of water.

Thus, percentage of the aquarium filled with water is;

(6039/167352) × 100% = 3.61%

Approximating to nearest percent gives; 4%

Subtract 5y ^ 2 - 6y - 11 from 6y ^ 2 + 2y + 5 .

Korvikt [17]

Step-by-step explanation:

$(6 {y}^{2} + 2y + 5) - (5 {y}^{2} - 6y - 11) \\ = 6 {y}^{2} + 2y + 5 - 5 {y}^{2} + 6y + 11 \\ = 6 {y}^{2} - 5 {y}^{2} + 2y + 6y + 5 + 11 \\ = {y}^{2} + 8y + 16$

Find the distance between the two points given (-2,6) and (-2,18)

Natasha2012 [34]

Answer:

Step-by-step explanation:

Let the two points be represented by (x1,y1) and (x2,y2).

Distance between the two points is given by the formula:

$\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}$ ----------------- (1)

In this case x1=-2,y1=6,x2=-2,y2=18.

Substituting the relevant values in the formula (1),

distance = $\sqrt{(-2-(-2))^{2}+(18-6)^{2}}$

= $\sqrt{0^{2}+12^{2}}$

=12
